Our Verdict on Each
An incredibly efficient 6-core CPU that delivers excellent everyday desktop performance with near-silent operation, perfect for compact builds.
Best for: Building a silent or compact PC where heat output is the primary concern.
Read the full reviewAn excellent budget gaming CPU with high clock speeds and 20MB of cache, perfect for users who already own a dedicated GPU.
Best for: The Core i5-12490F is an excellent buy if you are building a budget gaming rig and can find it at a price lower than the i5-12400F or i5-12500. Because it lacks integrated graphics, you must pair it with a dedicated GPU. The higher clock speeds and 20 MB of L3 cache give it a slight edge in gaming over the 12400F. However, if the price is identical to the 12500, the 12500 might be preferable due to its included UHD 770 graphics. Ensure you pair it with a B660 or Z690 board to maximize value and features.
